July 7, 1931. A. P. ASHER TOOL FOR REMOVING DENTS FROM METALLIC BODIES Filed Oct. 29, 1929 Patented July 7, 1931 -ALLEN 1P. ASHER, OF SANDPOINT; IDAHO TOOL'IOR REMOVING. DENTS FROM METALLIC BODIES Application filed October 29, 1929. Serial. No. 403,248.

Y This invention relates to tools for removing dents fr'oinmetallic bodies, more particularly automobile fenders, doors or other portions ofan automobile body. v

The primary object of the present invention' is to provide a tool which may be securely attached to the body'to be worked upon such for examplefas a motor vehicle fender, or to a: suitable adjacent supportand operateda-gainst the inner surface of the body to force outwardly any indentations therein so that the outer surface of the body will be restored to its original contour.

Another object of the invention is to provide a dentremoving tool for metallic bodies which includesa rolling element adapted to be moved over the dented surface against the convex portion thereof; in an arc applyin'g rolling pressure thereto for the purpose ofrestorin'g the dented portiontoj its normal or original position.

Still another object of the invention is to provide a dent removing tool which is adaptedto work against the bead of amo'tor vehicle fender for the removalof d nts herefrom. A a a "The invention broadly contemplates the provision of a supporting f ame iniWhi Q l isfoscil latably mounted ia' block through which extends a shaft, theshaft being in threaded engagement with the'block so that itirnay be fedtherethrou'gh as desired to position a imandrel wheel carried upon the inner end properly with respect to a dent in the adjacent body; The block carrying the shaft is somounted that the shaft may be swung in a plane attright angles tothe block and the block supporting frame isso mounted as to permit its oscillation ina plane transversely of the plane in which the shaft is swung.

Thei i n e i e e t er tood from. a considerationqof; the following 'detailed description taken in connection: with the accompanying; drawings forming part of this specification, withthe' understand ing, however, that the invention is not confi d ny St t wnf rm ty wi t h w g f i h rawings a. b t; maybe changed or "modified so long-as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure l is a view in transverse section through a motor vehicle fender showing the device embodying the present invention applied thereto.

Figure '2 is a front elevational view of the supporting frame for the tool.

Figure 3 is aface View of the mandrel roller.

Referring more particularly to the drawings wherein like'numerals of reference indicate corresponding parts throughout the several views, the tool embodying the present invention is shown as applied to a motor vehicle. fender, the fender being indicated generally by the numeral 1, the outer edge or rim portion thereof being indicated by 7 thereof and which has the ends turned inwardly as indicated at 6' and attached to the straight bar 4 adjacent the ends of the same in the mannershown, the extended end portions of the bar 4 being slightly reduced and of circular cross-section as indicated at 7. l

At each, end of the bar 4 a clamp 8 is mounted. These clamps are preferably of the type known as G clamps, those used in association with the present tool preferably having a relatively deep throat. The frame of each of the clamps 8 is provided with a series oftransverse apertures 9 in one of which the reduced portion 7 at one end of the bar 4 is adapted to position, the clamp being prevented from disengagement from the bar by a nut or by any other suitable means.

Removably positioned in each of the bars and- 5 midway betweenthe ends of the frame are bearing points 10fwhich as shown are directly inal-igiiment transversely of the rame, nd osc ll ta y m un ed b we n these bearing points is a block ll'through sage 12 is formed." a
